Let's divide 77344487 by 91
Our goal is to divide 77344487 by 91.

Advancing to step 1:
7 divided by 91 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 91

On to step 2:
The number 91 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 91

Let's proceed to step 3:
The number 91 fits into 773 8 times, leaving a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 45 after subtracting 728 from 773.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 91

Step 4:
The number 91 fits into 454 4 times, leaving a remainder of 90.
Put 4 as the next digit of the answer. 
Result so far: 84.0
The remainder is 90 after subtracting 364 from 454.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 91

Going ahead to step 5:
If we divide 904 by 91, we get 9 and a remainder of 85.
The next digit of our result is 9. 
Result so far: 849.0
Deduct 819 from 904 and we're left with 85.
Fetch the next digit (4) from the dividend, attach it to 85 and continue: 854 / 91

On to step 6:
The number 91 fits into 854 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 8499.0
If we subtract 819 from 854, we get 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 91

Step 7:
91 goes into 358 3 times with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 84993.0
If we subtract 273 from 358, we get 85.
Bring next digit (7) of the dividend behind the 85 and repeat the process: 857 / 91

On to step 8:
91 can be fit into 857 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 849939.0
Subtract 819 from 857 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
91 can be fit into 380 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 849939.4
Deduct 364 from 380 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 91 is 1 with a remainder of 69.
The next digit of our result is 1. 
Result so far: 849939.41
Subtracting 91 from 160 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 11:
If we divide 690 by 91, we get 7 and a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 849939.417
Deduct 637 from 690 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 12:
530 divided by 91 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 849939.4175
Deduct 455 from 530 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
If we divide 750 by 91, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 849939.41758
If we take 728 away from 750, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
220 divided by 91 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 849939.417582
If we take 182 away from 220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 15:
When dividing 380 by 91, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 849939.4175824
If we subtract 364 from 380, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
The number 91 fits into 160 1 times, leaving a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 849939.41758241
If we take 91 away from 160, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final outcome is 849939.41758241, with a leftover of 6.9e-08.
